Ullmann condensations of diarylamines with iodobenzenes has been investigated under homogeneous and a heterogeneous catalytic conditions with cupruos and cupric salts, as well as powered copper metal.Copper catalyzed condensation of diarylamines with iodoaromatics is relatively insensitive to substituent (for substituted iodobenzenes p=-0.25; for substituted diphenylamines p=1.09) but quite sensitive to halogen (k1/kBr.200).The first direct evidence for solution catalysis after filtration of a metal catalyzed reactions was obtained.Quantitative analysis of reaction rates, product yields, and catalyst characteristics leads to a comprehensive picture of the formation of soluble cuprous ions as the single active catalytic species under all conditions investigated.This hypothesis rationalizes many of the perplexing results which typify the literature associated with copper catalyzed nucleophilic aromatic substitution.

Equimolar reaction of copper(I) bromide with 2-thiouracil (tucH2) in acetonitrile-methanol formed a light yellow solid which on subsequent treatment with a mole of triphenyl phosphine (PPh3) in chloroform has yielded a sulfur-bridged dinuclear complex, [Cu2Br2(mu-S-tucH2)2(PPh3)2] 2CHCl3 1. A reaction of copper(I) bromide with two moles of 2,4-dithiouracil (dtucH2) in acetonitrile-methanol followed by addition of two moles of PPh3, designed to form [Cu(mu-S,S-dtuc)2(PPh3)4Cu] 2a, instead resulted in the formation of previously reported polymer, {CuBr(mu-S,S-dtucH2)(PPh3)}n 2. Reaction of copper(I) iodide with 2-thiouracil (tucH2) and PPh3 in 1:1:2 molar ratio (Cu:H2tuc:PPh3) as well as that of copper(I) thiocyanate with pyridine-2-thione (pySH) or pyrimidine-2-thione (pymSH) and PPh3 in similar ratio, yielded an iodo-bridged unsymmetrical dimer, [(PPh3)2(mu-I)2Cu(PPh3)] 3 and thiocyanate bridged symmetrical dimer, [(PPh3)2Cu(mu-N,S- SCN)2Cu(PPh3)2] 4, respectively.

Redox catalysis has been broadly utilized in electrochemical synthesis due to its kinetic advantages over direct electrolysis. name: Bis(acetylacetone)copper.

Copper-containing MOFs are found to be active, stable and reusable solid catalysts for three-component couplings of amines, aldehydes and alkynes to form the corresponding propargylamines. Two tandem reactions, including an additional cyclization step, leads to the effective production of indoles and imidazopyridines. In particular, the lamellar compound [Cu(BDC)] (BDC = benzene dicarboxylate) is highly efficient for the preparation of imidazopyridines, although a progressive structural change of the solid to a catalytically inactive compact structure is produced, causing deactivation of the catalyst. Nevertheless, the phase change can be reverted by refluxing in DMF, which recovers the original lamellar structure and the catalytic activity of the fresh material. The use of [Cu(BDC)] for this reaction also prevents the formation of Glaser/Hay condensation products of the alkyne, even when the reaction is performed in air atmosphere. This is a further advantage of [Cu(BDC)] with respect to other homogeneous copper catalysts, for which the use of an inert atmosphere is necessary.

Complexes 1?3 can act as yellow luminophores, complex 4 acts as a red luminophore, complex 5 acts as an orange luminophore and complexes 6?7 act as green luminophores.

The syntheses, spectroscopic characterization (IR, 1H and 31P NMR, ESI-MS) and conductivity studies of the mixed N,P-donor complexes of copper(I) thiocyanate: [Cu(NCS)(py)2-(PPh3)], (2), [Cu(NCS)(Mepy)(PPh3)]2, (3), [Cu(NCS)(phen)- (PPh3)], (4), [Cu(NCS)(bpy)(PPh3)], (5), [Cu(NCS)(bpy)-(PPh2py)], (6), [Cu(NCS)(py)(PPh2py)], (7), (py = pyridine; Mepy = 2-methylpyridine; phen = 1,10-phenanthroline, bpy = 2,2?-bipyridyl), together with single-crystal X-ray structural characterizations of 2, 3, 4 (new polymorph), 5 and 6 are reported, which provides an opportunity to study the effect of the introduction of a pair of nitrogen donors, both unidentate and chelate, on the bonding parameters of the Cu/NCS/P system. Cu-P and Cu-N2(ar) are found to be similar [2.1974(5) and 2.091(2), 2.070(1) A for py2 adduct 2, cf. 2.1748(9)-2.200(1) and 2.071(2)-2.106(4) A for the counterpart values for bidentate adducts 4-6]. However, Cu-N(CS) and Cu-N-C are 2.013(2) A and 157.4(2) for py2 adduct 2 and 1.946(2)-1.981(8) A and 166.7(2)-176.58(2) for bidentate counterparts 4-6. The change is attributed primarily to the closure in the N-Cu-N angle [99.58(8) for py2 2; 77.7(6)-80.5(3) for N?N-bidentate donors 4-6]. In consequence of the increased steric profile of the Mepy ligand, we find the stoichiometry diminished to 1:1:1, which resulted in the formation of [(Ph3P) MepyCu(NCSSCN)Cu(Mepy)(PPh3)] dimers. TDDFT/CPCM calculations were used to clarify the type of transitions involved in the UV/Vis absorption spectra, and the corresponding experimental photoemission data were acquired. The 31P CPMAS spectra of the copper derivatives exhibit distorted quartets that afford values for 1JCu,P. Furthermore, the quadrupole-induced distortion factors were calculated, and in the cases of 2, 4 and 5, the quadrupole coupling constants were obtained, on the basis of the X-ray structures.
